How to inflate the icon image in my layout?

Question

I am trying to add a small home icon image to top of my list view.Below you can see the code of my adapter. It works perfectly for setting dynamic text but it fails when i want to add an image.

I do not get any runtime error, just the images aren't loaded.

The images referenced are 35x35 png file.

How to implement this? Im new to android. please guide me.

      LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      viewList = Nexttopic.this.getLayoutInflater().inflate(R.layout.activity_nexttopic, null);
      dialogMarketList = new Dialog(Nexttopic.this);
      dialogMarketList.requestWindowFeature(Window.FEATURE_NO_TITLE);
      dialogMarketList.setContentView(viewList);
      dialogMarketList.show();     
      lvForDialog = (ListView) viewList.findViewById(R.id.List_view);
      lvForDialog.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
      ArrayAdapter<String> adapter = (new ArrayAdapter<String>(Nexttopic.this, R.layout.row_topic, R.id.child_row,tnamelist));
      ImageView home = (ImageView) findViewById(R.id.hme);
      lvForDialog.setAdapter(adapter);
